PartyMode 2.0 is an audio-reactive lighting system that can also be used for illumination, documented at Cemetech. This compressed folder contains PartyModeFFT.ino, the Arduino source code for the firmware used in the project. The audio-processing code was partially inspired by the Piccolo project (https://github.com/adafruit/piccolo), and PartyMode requires the FastFFT library. It also includes an Android app to control the system and the Eagle PCB files for the low-voltage controller.
